TYPE-WRITER DESK.

SPECIFICATION forming part of Letters Patent No. 583,601, dated June1,18'97.

Application filed October 5, 1896.

To all whom it may concern Be it known that I, JULIUs F. MEISSNER, acitizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented certain new anduseful Improvements in Type-Writer Desks; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

The present invention relates to a certain new and useful type-writingdesk, and more especially to the mechanism for throwing the type-writingmachine in or out of sight; and it consists in the arrangement of partsand details of construction, as will be hereinafter fully set forth inthe drawings and described and pointed out in the specification.

The object of the invention is to provide simple and inexpensiveattachment mechanism for raising and lowering the type-writing machinein order to throw the same in and out of sight, which mechanism shall beso constructed and arranged that very little power shall be required toraise or lowerthe machine in order that the operator will not have tohandle the full weight of the machine.

In order fully to comprehend the invention, reference must be had totheaccompanying sheet of drawings, wherein- Figure l is a perspective viewof a typewriter desk, showing the mechanism for raising and lowering themachine in an open position or the position assumedv when the machine isexposed to View. Fig. 2 is a vertical cross-sectional end view of thedesk, taken on the medial transverse line of Fig. l; and Fig. 3 is asimilar view of the position of the parts when closed to hide from viewor cover the machine.

In the drawings the letter A is used to indicate the desk, which isprovided or made with the central open portion A. NVithin the centralopen portion, between the sides A2, is fitted and works the slidingplatform B, upon which platform is secured in any suitable manner thetype-writing machine. The ears a, depending from the under face of theplatform, near its inner end, are secured by pins a' to the lower en dof the main levers B. There are two of these levers, although only oneis shown, one being fulcrumed by pins a2 to each side A2 of the centralopen serial Nn. 607,836. (No model.)

inner edge of the lock-rail C, which raill is secured to the sides A2.The platform B rides upon the rolls b2 as moved in or out within thecentral opening of the desk.

To each side A2 is secured or fastened a guide rail or plate C', againstthe under edge of which the upper face of the platform B rests when theplatform is moved outward to exposethe type-writing machine, Figs. l andand 2, the platform then resting between the guide-rails and the rollsb2.

The cover B2 is provided with a front C2, which when the cover is thrownupward rests upon the lock-rail C. This front has attached thereto alock which engages with that of the lock-rail. To the front is alsosecured the handle C2, by means of which the cover is moved back andforth. In order to steady the cover as thrown back and forth, connectionis made through the medium of the arm D between the said cover and theguide-rail C', Figs. 2 and 3. For the purpose of closing the openingwhich would exist between the back plate B3 and the front C2 of thecover when the platform B is moved outward I secure to the back plate B2the right-angularlyextending piece or flange D.

To the forward edge of the central cut-away portion of the desk-top isattached the strip D2. This strip covers the joint between the inner endof the cover and the edge of the desk and at the same time answers as astop to prevent the pens or pencils rolling off the desk.

When the parts stand in the position illustrated in Fig. 3, beingclosed, the type-writing machine, resting upon the platform B, will becovered or hidden from view. To throw the machine into view for use, theoperator takes hold of the handle CS and by slightly lifting thereonraises the cover B2. As the IOO cover is raised its inner end Will movedownward or disappear Within the central opening 0f the desk, and themain levers turning upon their fulcrumed point the platform, with thetypeWriting machine attached thereto, Will gradually move outward andupward until it assumes the position illustrated by Figs. l and 2, whichis an open position. The type- Writing machine will then be exposed andin position for use.

Having thus described my invention, what I claim as new, and desire tosecure protection in by Letters Patent, is-

The improved type-Writer cabinet herein described and shown consistingof a desk having a central opening, guide-rails secured on the sideWalls of said opening at the top of the same, a lock-rail in front ofsaid opening, rollers mounted on the lock-rail, a platform slidingbetween said rollers and the lower edges of the guide-rails, saidplatform being provided With a back plate near its rear end and arearward extension or shelf extending from said back plate, a coverresting on the upper edges of the guide-rails, a front plate secured tosaid cover and adapted to engage the loclorail, levers fulcrumed on theside Walls of the central opening in the desk and having their oppositeends pivoted respectively to the platform and the cover and links havingtheir opposite ends pivoted respectively to the cover and theguide-rails.

In testimony whereof I affix my signature, in presence of two Witnesses,this 12th day of September, 1896.
